We visited an East End basement bar years ago in the style of the owner’s East European babushka’s home and some pretty weird cocktails - eg a glass pipe with a liquid, you pour another liquid and it “smoked”.
Went to the Aqua rooftop bar the other day - it was ok.
Can anyone recommend good options that are unique?
If it’s a “classic” cocktail experience you’re after then some of the high end hotels have good spots. The Connaught Bar and the Library Bar at the Lanesborough are very nice (quite expensive though and a bit stuffy).
Personally I’m a fan of Bar Américain at Brasserie Zédel.
Cahoots is another decent cocktail bar with a London Underground theme (set in an old station).
Not a cocktail bar but the Southbank Centre has a cool rooftop garden area with a small bar.
